Before we go on, here’s a spoiler alert for anyone who hasn’t yet watched the series finale.

The self-centred protagonist Hannah (played by Lena) welcomed a baby boy after getting pregnant by holiday fling Paul-Louis, played by Rogue One actor Riz Ahmed, and decided to name the baby Grover.

And no she didn’t name him after Grover from The Muppets.

Talking about the unique name choice, she explained to the Hollywood Reporter: ‘I came in one day and I was like, “The baby’s name is Grover.” And we were like, “Sounds about right.” We were kind of trying to figure out what kind of slightly off name Hannah would give her child.

‘And then it was Jenni who had the idea to have Paul-Louis say [that he thought] Grover would be a really nice name for a baby. Like, I want there to be some evidence that he is the father and that he mattered,’ she added.

The 30-year-old also added that when the name was put in, it felt so ‘beautiful and natural,’ but it was an odd enough name for Lena’s character to be comfortable with and not as crazy as naming the child Plutonium.

Although most fans of the show were sad to see the end, others were disappointed that once again ‘a woman’s happy ending’ had to come from her having a child and took to Twitter to voice their opinions.

Once again a woman's happy ending comes from having a child. I thought #GirlsHBO would be different. I was wrong. #childfree ?
